"It just shows you how much diversity we have here," Chen said. "How many teams say they can have a World team and a USA team? We legitimately have enough pitchers and position players to fill every single position -- on both sides."

Nate Adcock of Elizabethtown, Ky., is listed as the first USA pitcher, followed by Tim Collins, Michael Mariot, Chris Dwyer, Blaine Boyer and Donnie Joseph. Each pitcher is scheduled to throw one inning or 20 pitches in the 6 1/2-inning game.

Nitpickers might spot some discrepancies in the substitutions, however. George Kottaras, scheduled to be the second USA catcher, was born in Canada. Minor League outfielder Chad Tracy, born in Illinois, is listed as a World backup.

There will also be an intrasquad game on Wednesday. No word yet on any geographical divisions.

None of the Royals' front four starting pitchers are scheduled to pitch in the intrasquad games. James Shields, Jeremy Guthrie, Ervin Santana and Wade Davis did, however, pitch batting practice on Monday.

"It was top-notch," Yost said. "It was exciting to watch their focus and concentration."
